STEAM HUMIDIFIER.

Application filed August 14, 1923. Serial No. 657,458.

To all whom it may concern: y

Be it known that-I, ELwoon B. AYRES, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Steam Humidifiers, of whichthe following is a specification.

The object of my invention is to construct a humidifier for a drying machine, which will allow steam to escape freely into a chamber of a drying apparatus, and which will collect and will'carry off any water of condensation, due to the cutting off of the steam during the drying operation, which usually collects in the system.

In the accompanying drawings:

' Fig. 1 is a perspective view of my improved humidifier;

Fig. 2 is a longitudinal sectional view;

and

Fig. 3 is a transverse sectional view on the line 3-3, Fig. 2, showing a portion of the drier in dotted lines.

Referring to the drawings, 1 is a base, in the present instance, of a channel beam. 2 and 3 are standards, which carry the steam drum. The standard 2 has a cylindrical projection 5, into which extends one end of the drum 4, The opposite end of the drum extends into an opening, in the standard 3,

3 as clearly shown in Fig. 2. The standard 8 is in the form of a trap forv the water of,

condensation. p

6 designates a waste passage in the standard 3 for the water of condensation. This waste passage communicates with a waste pipe 7. Located within the drum 4 is a steam'pipe 9. This steam pipe is screwed into the projecting portion 10 of the standard 2. Coupled to this standard is a steam supply pipe 11. The opposite end of the pipe 9 extends through a bearing 12 inthe standard 3 and is closed by a cap 13. On the pipe is a'threaded collar 14. Between the collar and the bearing 12 is a rubber gasket 15. In the steam pipe 9 is a series; of perforations 16, spaced a given distance apart, and located on the under side of the pipe for the free escape of steam and any water of condensation from said pipe.

In the drum 8 are two seriesofperforations 17 and 18. The perforations 17 are in the lower portion of the drum and the perforations. 19 are in the upper portion of,

the drum. This permits the free escape of steam from the space within the inner drum 8 to the space within the outer drum 4.

As the perforations 17 areon the under side of the drum, the water of condensation escapes from the drum and flows to the waste passage 6.

7 It will be noticed that the humidifier is inclined towards the standard 3.

In the upper side of the outer drum 4 are perforations '19, through which dry steam escapes. This dry'steam escapes from the drum into a chamber a of a drying, or other, 1 machine, a portion of which is shown by dotted lines in Fig. 3.

By the above construction, it will be seen that the humidifier may be placed in any position in a drying apparatus without the liability of the water of condensation escaping into the drying chamber and being splashed on the material being dried, or dripping thereon, if placed above the material.

By making the humidifier with a central steam pipe and two drums, one within the other, the steam escaping from the outer drum will be dry, as the water ofcondensation will collect in the two drums and will escape freely through the passage 6.

I claim:

The combination in a humidifier, of two standards, one of greater height than the other, each standard having an integral cylindrical projection; two inclined drums, one

drum being located within the. other, each drum extending into the cylindrical projections of the standards; and a steam pipe extending through the inner drum and coupled to the standards, the lowerv standard having a waste passage formed therein and communicating with the outer drum, said outer drum being perforated at the upper side, the steam pipe having a series of perforations at the under side, the inner drum being perforated at the upper side and at the under side.
